IMPROVEMENT IN WINDNIILLS.

Specification forming part of Letters Patent N0. 53,45S, dated March 27,1866.

To all whom it may concern:

Be it known that I, PHILIPP LOEFFLER, of Milwaukee, in the county ofMilwaukee and State of Visconsin, have invented a new Improvement inConstruction of WVindmills or find-Power Apparatus and I do herebydeclare that the following is a full, clear, and

the plan or top view of the said wind-power.

Similar letters of reference indicate corresponding parts Vin bothgures.

This invention relates to a new and useful mode ot' constructing andattaching windmillpaddles to a frame in a horizontal position, also theconstruction ot' each paddle and movable plates, as hereinafter setforth.

To enable others skilled in the art tomake and use my invention, I willproceed to describe its construction and operation.

I construct my wind-power apparatus of aA frame, AA, Figs. l and 2, tiedtogether with stay-rods or braces, B B, with a center shaft, C,revolving as usually. On said shaft there are eight radial paddles orarms, (orlany number may be used.) Attached to secure said paddles tothe shaft are circular plates o o, fastened as shown on Figs. l and 2.Those circular plates and the paddles are revolving with said shaft,connecting said shaft with any required machinery in any ordinarymanner.

The paddles are constructed of two horizontal beams, P p', extended toany required length. Between said beams four movable plates, t tt t,(see Fi gs. 1 and 2,) are secured, so that when the paddle is movingagainst the wind the said plates are open, as shown in Figs. l and 2, tt t t, and when the paddle is operating in the current of wind the saidplates shutA themselves, (see` letters 1*/ t t t in both iigures,) bythis means regulating itself and making as little back friction aspossible, thus gaining power byits simple, durable, and easy mode ot'construction. In regard to keeping the said plates t t tt within a givenposition to open them, there are stop-pins w a: m x behind each plate,secured to the paddle-beams; and if required to stop the motion of thewindmill, partly or total, there is another guiderod, S, with stop-pinss s s s, in Fig. l, With lever L attached, so that when the said leveris raised the stop-pins enter between the movable plates and keep themin an open position, so that the wind will have no effect upon the sameand the mill will stand still.

Those paddle, as before said, are attached to the said center shaft intwo or more rows, one above the other, and in the accompanying drawingsthere are eight paddles in two rows. The paddles p p pp' (four innumber) are attached in the lower row, and the paddles P l? P P areattached in the upper row, in the manner shown on Fig. 2, each paddlecrossing the other, so that the wind may blow in any direction thepaddles must receive the full current of wind. The said paddles may beattached to a new or old windmill very easily, and are so plain andsimple in their construction that they cannot easily get out of orderand can be much cheaper manufactured, thus of great value to the countrygenerally.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The guide-rod S, having the stop-pins s s and operated by the lever-armL, constructed and operated as described, and arranged in relation tothe arms and paddles, substantially as set forth.

PHILIPP LOEFFLER.
